[Also in Division F2] A plurality of identical individual valves 1a, 1b, 1c ...., Figs. 1 & 2, are mounted together to form a valve assembly block 30, Fig. 12, having sequentially pressurized inlets 35 and outlets 36 connected to fluid operated devices (not shown), means (Fig. 8) being provided whereby any selection of valves can be closed to provide a predetermined programme of pressurization of the outlets 36. Each valve has a plunger 12 urged by a spring 14 to a withdrawn position in which a valve member 8 is free to engage one or other of two seats 6, 6a. Each valve member 8 engages its seat 6 when acted upon by pressure from its inlet passage 1, 2 or 3 connected to the inlets 35 and this position allows flow from the inlet to a transfer passage 7. This condition is shown by the valve 2a in Fig. 2. If the valve receives fluid from the transfer passage 7 of an adjacent valve, as shown by valve 3a, the valve member 8 engages the seat 6a and allows flow to its transfer passage 7 which may be connected to one of the outlets 36. The valves are closed by depression of their plungers 13. A number of ways of selectively closing the valves are disclosed. As shown in Fig. 8 a pivoted plate 17 having perforations 20 arranged to align with the valve plungers 13 is used. By obturating the selected perforations by means of caps, buttons or punched card 21, the plungers 13 are depressed when the plate is pivoted. Alternatively each valve to be closed may be provided with an individual detent for holding its plunger depressed, Figs. 22-25 (not shown) or a pneumatically operated spring loaded piston, Fig. 26 (not shown). The valves shown in Fig. 12 are held in assembled relationship by plates 31, 32, 33 forced by screws 34 against a frame 29 so that the flat faces of the valves contact.
